PC Turns Off Then Back On Again

[Chris J]

i recently upgraded to a RTX 5070Ti and ive been testing games on it all worked fine with no issues. But today i played Cyberpunk at 4K with Path Tracing for a while. I quit the game and went back to desktop and started downloading a game on steam. as it was downloading i was casually browsing youtube etc. Then all of a sudden my PC switched off and restarted itself.


these are my full specs.

CPU: i9-10900k 10 cores 20 threads @5.1Ghz
COOLER: Corsair H100x AIO
GPU: RTX 5070Ti Gigabyte Windforce OC 16GB
RAM: 32GB Crucial DDR4 3600mhz Dual Channel
MOBO: MSI Z490 Tomahawk
SSD: Samsung 980 Pro 2TB (for games)
HDD: Seagate Ironwolf 10TB 7200rpm
PSU: Seasonic Focus GX 1000w Gold
Display: LG 4K C3 OLED
Operating System: Windows 11 Pro

This (random restarts) is usually caused by a faulting and/or insufficient power supply, so that would be the first thing i'd check.

i have a Seasonic Focus GX-1000w which is a really good quality PSU it seems unlikely. I noticed this issue happening when i sat letting the shaders build on Last Of Us Part 1 too

Check everything is seated properly, you may have loosened something when changing the GPU.

it could be your ram, as it is a ram speed that is not recommended for your cpu. the recommended ram is DDR4-2933. though it could also be that your gpu overheated. maybe you should try to set the ram speed to 2933 and see if the problem is solved.

Doesn't matter. It's all about the internals, and it can always fail no matter the brand or build quality.

The fact this is happening more means you really should check it. Swap for another at the very least, even if it's older.

If it doesn't cure it, you know it's something else in the PC. Eliminates something from your checklist. If it does, you know you need to RMA the Seasonic, or buy a new one if it's out of warranty.

Trying it in another PC is also a potential test you can do. Lend it to a friend even... Anything to test it.

You can attempt to limit voltages and underclock your CPU if you so wish, but easiest test is swapping the PSU.

I.. don't. Personal experience in the past with Corsair stuff has not been the best... That actually makes me consider pointing the finger at it moreso than less....

Check the event viewer logs and see what is showing in there.

I'd be inclined to agree that the first guess would be PSU related if it is in fact a full system reseting.

However, given the recent change in your hardware was only the GPU I'd be more inclined to suggest it is more likely the GPU driver crashing the windows kernel which the default behavior would be to reset. (e.g. a BSOD but you aren't seeing the BSOD because the GPU driver isn't working so essentially you are having a screen blank and then a BSOD after the screen blank which then resets).

It could also be memory as noted above but given the PSU and memory is a pretty decent quality parts I'd lean more toward the thing you changed recently as the first point of attack.

1. Download the latest nVidia drivers
   
2. Use DDU in safemode to wipe the GPU drivers and disable windows update so that Windows doesn't install it's WDM driver after you reboot.
   
3. Reboot back into normal mode and install the drivers you downloaded previously
   
4. Reboot when prompted after the driver installation
   
5. Download Passmark Burn-in-test trial version and/or make a Memtest86+ boot disk
   
6. Boot to either tool and run a full memory test to see if you have any memory errors and if so isolate each memory module and re-test to figure out which memory module(s) you should replace. Also, make sure to try the memory in a different DIMM slot as well to rule out the DIMM slot / memory channel being the issue and not the memory module.

If doing this results in all of the memory testing OK and reinstalling the GPU driver cleanly doesn't resolve the issue, retry doing the clean GPU driver installation with an older (but still supported version for your 50-series card) driver. If that still doesn't resolve it then you might want to either get a good PSU tester (which can be pricy for one that actually properly tests them) or have your PSU tested by someone who has a good PSU tester. Alternatively, you could also try to replace your PSU with a different one to test if that resolves the issue; but either way I'd leave that portion of troubleshooting to the end as I'd doubt it's your problem.

I would check the PSU as well.
Here is a current story with a Corsair psu.


Another RTX 5090 connector melts down, reportedly taking a PSU with it
Melting occurs despite Corsair's first-party 600W 12VHPWR cable being used.

[_I_]

unplug all usb devices
bios can be configured to turn on to k/m or other devices

may even be timer or wol, check all the power settings

this is a seasonic power supply not corsair

Seasonic are the ones who *make* Corsair units. They are the same inside the box.

It's the same thing with other brands. EVGA, despite high praise for their PSU's, did not make their units either.

But i'd seriously suggest testing it. This won't go away on it's own.

i reseated some of the power supply cables like the PCI Cables and the CPU Cables today took it all out and plugged them back in tightly ill test some more today. Ill also undervolt my CPU and see if that helps if it does ill probably go and buy a different power supply

For clarity, Seasonic makes some of Corsair's PSU models. Most of the mid to lower end series are manufactured by CWT (Channel Well Technology). Such as most of the RM, CM, CM-X series are made by CWT; with most of the RMx, HX, and AX series models being made by Seasonic.

I'd also concur with testing the PSU but as I noted previously it is far more likely their issue is with what they have recently changed when the issue started. There have been several driver stability issues with the most recent few NVIDIA drivers so a good starting point would be to fully wipe them with DDU and prevent Windows from auto-installing it's WDM driver; then doing a clean install of the current driver. Then try to repeat the process and roll back through the prior driver versions (that support the 50-series) and re-test for stability. Along with testing their memory, if this doesn't resolve their issue then it'd make sense to test the PSU with an actual PSU tester (not the $20-$30 trash ones)

before i installed the card i removed the drivers with DDU and then turned the PC to install my new card. kept the internet cable out. And i installed the driver the 5070Ti then i plugged the ethernet cable back in and restarted the PC everything was working fine played Last Of Us Part 2 4K max settings. Even played Cyberpunk yesterday all worked good. Its only when i went on the desktop and went to download and install a big 70gb game on steam my PC just switched off then came back on again like it restarted itself

Seasonic is a good quality PSU. I think Liquid was more suggesting that even good quality PSUs can fail / have issues and the issue you described is often attributed to failing / bad PSUs so it'd be worth testing it to verify it's working properly.

How long have you had it prior to your GPU upgrade, and I'm assuming contextually from your OP that you had no issues with it prior to getting your new GPU correct?
